MULTICHANNEL OPTICAL SPECTROMETER Russian patent published in 2015 - IPC G01J3/20 G01J3/50 G01J3/36 

FIELD: physics.

SUBSTANCE: spectrometer includes arranged on a Rowland circle, an entrance spectral slit, a concave diffraction grating and a multichannel radiation detector. The radiation detector consists of flat multielement photodetectors placed in housings. Each photodetector is further provided with a fibre-optic focusing cone, the flat end of which, on the side for mounting onto the surface of the multielement photodetector, has a width which is greater than that of the multielement photodetector, but a shorter length than that of the multielement photodetector. The end of the focusing code on the optical radiation entrance side has a greater length than that of the housing of the multielement photodetector. Entrance ends of the focusing cones mounted on the photodetectors are arranged on a Rowland circle, and the edges of focusing cones of adjacent photodetectors touch.

EFFECT: high reliability of spectrometer readings.
